Summary

This study compares two ultrasound-guided injections for trigger finger, a condition where a finger gets stuck in a bent position. One injection uses betamethasone (a steroid), the other uses dextrose (a sugar solution). The goal is to see if dextrose, which may help tissue heal, works as well as the standard steroid treatment. Adults with trigger finger for at least four weeks can join, and the study measures pain, finger locking, and hand function over 12 weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
betamethasone and dextrose injections
What this could lead to
If dextrose works as well as betamethasone, it could offer a safer, regenerative option for trigger finger without steroid side effects.
What could go wrong
This is a small, early-stage trial with only 42 participants, so results may not apply broadly. Dextrose may prove less effective than the standard steroid treatment.
